A recent study highlights an unstated link between tiny plastic particles, or microplastics, in human blood and potential health risks.

Researchers in South Korea found evidence that these particles can disrupt the blood clotting process and potentially increase the risk of heart disease.

These particles are formed when plastic waste breaks into smaller pieces.

The study involved 36 healthy adults whose blood samples were analyzed for microplastics and markers related to blood clotting and inflammation. Surprisingly, microplastics were found in almost 89% of the participants, with an average of 4.2 particles per milliliter of blood.

The most common types of plastics found were polystyrene, often used in disposable cups and containers, and polypropylene, a material commonly found in food packaging.

Lifestyle habits, such as frequent use of plastic food containers, appear to be a major factor in high microplastic levels in the blood. People who relied more on such containers had significantly more microplastics in their bloodstream.

The study also found that those with higher levels of microplastics in their blood had significant changes in markers related to blood clotting.

For example, a key marker called fibrinogen, which helps form clots, was increased. These individuals showed higher levels of inflammation, as indicated by increased levels of C-reactive protein.

Although the exact health implications are still under investigation, the findings highlight the need for caution.

Problems with blood clotting can increase the risk of serious conditions like heart attack and stroke, raising concerns about the long-term effects of microplastics in our bodies.

Experts say that this research is a warning that our dependence on plastic is affecting not only the environment but also human health. “Reducing the use of plastics in daily life, such as avoiding plastic containers for food storage, is a small step we can take to limit our exposure,” the researchers said.

The study’s findings make it clear that tackling plastic pollution is not just about saving the planet, it is also about protecting our health.

Scientists urged more research to understand the widespread impact of microplastics on the human body and develop strategies to reduce exposure.

Microplastics are infiltrating every corner of our lives, from the water to the food we eat, now found not only in blood but also in saliva, spit, lungs, liver, breast milk and stool.
